How do I lower water without a main drain
Hello All - My CYA is over 100 and I need to dump some water and add fresh. My problem is that I don't have a main drain so I can only lower the water to the lowest point on the skimmers (2). I don't think that will be enough. I was thinking of getting a fitting to plug into the 1.5" line in the bottom of my skimmers that can have a flexible hose attached to it. I would then snake the hose out of the skimmer door and down into the pool. What does anyone think??
My info is as follows: 16x23 IG vinyl. 2 skimmers, 3 returns, 15,500 gallons, chlorinator (the culprit). My CYA is about 125. Any idea how much water needs to be exchanged? Thanks!
